Improvement in carping-machines



HENRY HIGGINS AND THOMAS s. WHITWORTH, or MANoHES'rER, GREAT BRITAIIMPROVEMENT IN CARDING-MACHINES.

Specification forming part of Letters Patent No. 161,613, dated April 6,1875; application filed September 2, 1874.

To all whom it may concern:

Be it known that we, HENRY HIGGINS and THOMAS SoHoFIELD WHITWORTH, ofManchester, in the county of Lancaster, Great Britain, have inventedcertain Improvements in Garding-Engines, of which the following is aspecification:

Our invention relates to those carding-engines which are provided withflats which are raised periodically by an automatic operation for thepurpose of being cleaned; and consists, first, in an arrangement bymeans of which the vibrating levers which convey the flats over thesurface of the cylinder are squared during their motion; secondly, in a.novel construction of the ends of the flats, which pass into the partsof the vibrating levers by which they are lifted.

In the accompanying drawings, Figure 1 represents, in side view, aportion of a carding-engine, with the first part of our inventionadapted; and Fig. 2, a cross-section of the same.

At a is the cylinder, upon the bends b of which are the flats c, thesaid bends bei ng formed, according to our invention, with toothed racks(I. At 0 are the vibrating levers, which are caused to vibrate by amangle-rack, or in any other ordinary manner and at f are the slidingpieces moving thereon, and which, when they are lifted by ordinaryapparatus, (not shown,) bring the pockets g onto the ends h of the flatsfor the purpose of raising them, to be turned over and cleaned in anymanner now in use. In gear with the bend-racks d are pinions i 6*,carried by a hollow shaft, j, and through this there passes a shaft, It,provided with pinions l 1*, taking into the racks m 411*. When the rackm is moved upward for the aforesaid purpose it communicates motion tothe other rack, m*, by means of the pinions l l the shaft k of which isloose within the hollow shaft j, and when the levers e are caused tovibrate they carry with them the said hollow shaft, which rolls thepinions i within the teeth d, and secures the square movement of thevibrating levers e.

The second part of our invention is shown at the detached views, Figs. 3and 4, and Fig. 5 is a detached View, which, although not claimed by us,is necessarily referred to in order to explain one object we have inview and this figure we will in the first place describe, but referringalso to Figs. 3 and 4, in which some of the same parts are shown. Uponthe frame is a flange, n, which carries a bolt, 0, capable of adjustmentupward and downward bynuts p, and having at its other end a flange, q,provided with an adjustable screw, 1". At 0 is the flat in its workingposition, one side thereof resting on the flange q and the other on theset-screw r, which, if it be raised or lowered, alters the heeling ofthe flat. When the pockets g, Fig. 2, ascend, it is, of course,necessary that the parts h of the flat shall be over them, so that theymay be received therein; but, by altering the heeling of the flat, thesaid parts h are necessarily turned on one side and out of their properrelative position, and one object of this part of our invention is tocorrect that disarrangement, and this we do by forming the parts It indistinct pieces and attaching them so that they may be adj ustable. Theflat is shown at 0, upon which is secured, by means of set-screws s, aplate, it, from which there projects the part h, which is to be receivedby the pocket 9. The set-screws 8 pass through slots to, and when theyare loosened the part It may be moved in one direction or the other, soas to bring it immediately over the line in which the pocket will beraised. But another object is attained by this part of our invention,for, supposing that no adjustment is required arising from an alterationin the heeling of the flats, our improvement facilitates the adjustmentof the parts in the original construction of the machine.

We claim as our invention 1. The combination, with the vibrating leverse, of the bends I), having racks d, and the shafts j k, having pinions ii and l 1*, as and for the purpose described.

2. A flat having the parts It made in separate pieces, and adjustable,as and for the purpose specified.
